Title: Filtering method by filter membrane
Inventor: NISHIMURA SHUICHI
IPC: C02F1/44
Filed: 1985-09-12
Abstract: PURPOSE:To prevent clogging, by filtering waste water containig fine silicon particles held to pH 7 or less by a filter membrane. CONSTITUTION:Waste water containing fine silicon particles is received in a pH detection tank 5 and the pH of waste water immediately after a discharge point is measured by the pH meter 6 provided to the pH detection tank 5. When the pH of waste water is 7.0 or more, an acid 7 is added so as to adjust pH to 4.0-7.0. Next, the waste water of which the pH was adjustedsis stagnated in a stagnation tank 1 and supplied to a recirculation tank 2 by a pump 8. The waste water in the recirculation tank 2 is supplied to a filter 3 by a pump 9 to filter the fine silicon particles in waste water through the surface of a filter membrane to obtain filtrate while the concentrate 11 is recirculated to the recirculation tank 2. By this method, filtering can be efficiently performed.

Abstract: PURPOSE:To form a fine electrode pattern and a semiconductor region on a substrate by covering a substrate with two types of resists having different photosensitive characteristics to cover it with resist films of 2-layer structure to form a sidewall. CONSTITUTION:Two types of resist films having different photosensitive characteristics are formed on two layers 2, 3, the film 3 of the upper layer is exposed, developed to form an opening 3a, and covered with an insulating film 4. Then, the insulating film on the resist film is removed by anisotropically etching to form a sidewall 4a on the sidewall of the opening 3a. Thereafter, with the upper layer resist film as a mask the layer 2 is exposed and developed to expose the substrate surface inside the sidewall, then coated with a metal film to become, for example, a gate electrode 5a or implanted with impurity, and the unnecessary resist film is then removed. Thus, the film 2 of the lower layer becomes a buffer layer in case of forming the sidewall to the sidewall of the opening of the film 3, and a fine electrode pattern or a semiconductor region can be formed on the substrate.

Title: Automatic playing device, automatic playing method and recording medium
Inventor: YAMAGUCHI YORIHISA
IPC: G10H1/00
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To adopt even the tones which are heretofore not selected as automatic accompaniment sounds as tension notes of assigned chord names. SOLUTION: A playing data supplying means supplies chord data including fundamental tone data, type data and available note scale data in one set as one piece of the chord data. The available note scale data indicates the specific available note scale data to be foundation for this chord (ought to be used corresponding to this chord). Then, a playing data forming means is now able to properly adopt tension motes which are heretofore prohibited to be used by referencing this available note scale data. The means is thus capable of forming the playing data of quintessence sounds. If the available note scale is a Mixolydian scale in, for example, a G seventh chord, the means is capable of forming the playing data by adopting the tones of the natural 9th tone (the tone of 'A') and the natural 13th tone (the tone of 'E') as the tension notes.

Title: Stationary frequency converter
Inventor: TADAKUMA SUSUMU
IPC: H02M7/48
Filed: 1994-08-25
Abstract: PURPOSE: To obtain a frequency converter with excellent response without heating problem by controlling a semiconductor element of an active filter in such a manner that an unbalanced current generated at a load will be absorbed. CONSTITUTION: Three-phase AC is concerted to DC by a converter CON (1), and DC is converted to three-phase AC by converter CON (2). When electric railcars are on both the feeders A and B or not on the feeders A and B, the load seen from the output side of the converter CON (2) becomes three-phase load, and the influence upon the power source system is small. If there is an electric railcar only on either feeder A or B, then the load seen from the output side of the converter CON (2) essentially takes a single-phase load, voltage fluctuation of 120Hz component appears in the DC circuit and this appears as a high frequency in the system at 50Hz side. To suppress this, an active filter ACF is inserted in the DC circuit, and the control is performed without transmitting the influence of fluctuation load to the power supply system without increasing the capacity of the capacitor.
